I have custom adapter in which i inflate layout. In adapter i try to change some text value in TextView (@id/datetextcal)

LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            cellView = inflater.inflate(R.layout.calendarcell, null);


         TextView dateText = (TextView) cellView.findViewById(R.id.datetextcal);
             dateText.setText(position);

I think that's all right but i have an error! why ?

Without modify this value all compiles and work correct.

code for layout(R.layout.calendarcell):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:background="@drawable/cell"
    android:orientation="vertical"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="40dp"
    android:layout_height="40dp">
    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center_vertical">
        <TextView
            android:id="@+id/datetextcal"
            android:text="2"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />
        <ImageView
            android:layout_alignRight="@id/datetextcal"
            android:paddingRight="2dp"
            android:src="@drawable/dropper"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </RelativeLayout>
    <TextView
        android:gravity="center_horizontal"
        android:textSize="9dp"
        android:text="заметка"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

code for adapter class:

package com.android.wcalendar;

import java.util.Date;

import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

public class ImageAdapter extends BaseAdapter
{
    private static final String TAG = "trace";
    private Context             mContext;

    public ImageAdapter(Context c)
    {
        // TODO Auto-generated constructor stub
        mContext = c;
    }

    @Override
    public int getCount()
    {
        // TODO Auto-generated method stub
        return 7 * 5;
    }

    @Override
    public Object getItem(int arg0)
    {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public long getItemId(int arg0)
    {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    // create a new ImageView for each item referenced by the Adapter
    public View getView(int position, View convertView, ViewGroup parent)
    {
        View cellView = convertView;
        if (cellView == null)
        { // if it's not recycled, initialize some attributes
            cellView = new View(mContext);
            Log.d(TAG, "cellView null");
        } else
        {
            Log.d(TAG, "cellView not null");
            cellView = (View) convertView;
        }
        LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        cellView = inflater.inflate(R.layout.calendarcell, null);

        // Date date = new Date();
        // date.setDate(position);

         TextView dateText = (TextView)
         cellView.findViewById(R.id.datetextcal);
         dateText.setText(position);
        return cellView;
    }

}

and that errors :

suggests there's something wrong with:

     dateText.setText(position);

Why would this lead to a message that says resource id 0x0 could not be found?

You're calling the resource version of setText(int) with an integer value that is not a valid resource id. Did you mean to call the string version of setText(String)?:

     dateText.setText(Integer.toString(position)); // or just setText(position+"")
